In Fossil Fighters: Frontier a new way of getting unlockable content was added to the series. Rather than having to download extra data from various distributions, printable AR Cards (Augmented Reality Cards) are available online for players to scan and bring certain Vivosaurs to life as well as unlock special Bone Buggies to drive around the game with. The original 9 AR Cards were released when the website went online, while Pyro Yutie and Master Maw were released on May 20, 2015.
AR Cards are separated by region and so scanning in a Japanese AR Card using an American copy of the game will not unlock any content. You can find all of the currently available AR Cards below.
